The first spoken dialogue system developed for the Persian language is introduced. This is a ticket reservation system with Persian ASR and NLU modules. The focus of the paper is on learning the dialogue management module. In this work, real on-line training data are used during the learning process. For on-line learning, the effect of the variations of discount factor (g) on the learning speed...

The uncertainty of renewable energy sources (RESs) presents a challenge for power grid operation. To analyze the variability RESs, probabilistic flow (PPF) method has been introduced. This can be used to evaluate RES generation and its effects on system voltage flow. In this study, an analytical approach with PPF calculate line sensitivity by is proposed, which directly probability distribution...

A time-dependent double-barrier option is a derivative security that delivers the terminal value φ(ST ) at expiry T if neither of the continuous time-dependent barriers b± : [0, T ]→R+ have been hit during the time interval [0, T ]. Using a probabilistic approach, we obtain a decomposition of the barrier option price into the corresponding European option price minus the barrier premium for a w...

In deterministic optimization problems, line search routines are a standard tool ensuring stability and efficiency. In the stochastic setting, no direct equivalent has so far been formulated, because uncertain gradients do not allow for a strict sequence of decisions collapsing the search space. We construct a probabilistic version of the line search paradigm, by combining the structure of exis...

We present a novel Hough Transform algorithm referred to as Progressive Probabilistic Hough Transform (PPHT). Unlike the Probabilistic HT [7] where Standard HT is performed on a pre-selected fraction of input points, PPHT minimises the amount of computation needed to detect lines by exploiting the difference in the fraction of votes needed t o detect reliably lines with different numbers of sup...

The blood-air barrier in the lung consists of the alveolar epithelium, the underlying capillary endothelium, their basement membranes and the interstitial space between the cell layers. Little is known about the interactions between the alveolar and the blood compartment. The aim of the present study was to gain first insights into the possible interplay between these two neighbored cell layers...
